# Issues with clockwise polar plot

I have a list of values representing radius (r) and another representing angles (theta). I am trying to make a polar plot with North as 0 deg, East as 90 deg and so on.

``````import matplotlib.pyplot as plt
import numpy as np

theta = [87.23008557164445, 100.26076015446364, 78.71990232378403, 136.34914122677247, 103.6118957767244, 108.8898592700267, 93.2079887669754]

r = [9.672704455052727, 5.747648969819628, 7.8846103848102835, 3.924182947507153, 5.631744483153131, 7.051601437489786, 2.2619972761713196]

colors = ['#c96253', '#e6b065', '#59c752', '#52c7bb', '#5260c7', 'w', 'k']

fig, ax = plt.subplots(subplot_kw={'projection': 'polar'})
ax.set_theta_direction(-1)
ax.set_theta_zero_location('N')

for i in range(0, len(r)):
ax.vlines(theta[i], 0, r[i], colors=colors[i], zorder=3)

``````

The angles in the list does not correspond to what is plotted. Does anyone know how to solve it?

### >Solution :

You need to put the theta parameter in radians. You can use `math.radians()` to do this.

``````import matplotlib.pyplot as plt
import numpy as np
import math

theta = [87.23008557164445, 100.26076015446364, 78.71990232378403, 136.34914122677247, 103.6118957767244, 108.8898592700267, 93.2079887669754]

ax.set_theta_direction(-1)
ax.set_theta_zero_location('N')

for i in range(0, len(r)):
